Embodiment 1

[0026] 1. Experimental materials

[0027] Jinhanjiang Refined Cotton Co., Ltd. produces 11 types of flocculent and rolled refined cotton: No. 5, No. 15, No. 30, No. 60, No. 100, No. 200, No. 400, No. 650, No. 1000, 2000, 3000.

[0028] 2. Experimental method

[0029] 2.1 GB / T9107 method

[0030] (1) Preparation of samples

[0031] Place the sample in a clean and dry pan, tear it loose and mix it evenly (non-fibrous impurities are not allowed to be removed), quickly take out the moisture sample to be tested, spread the rest of the sample with a thickness of about 20-30mm, and place it at room temperature for 4 After ~5 hours, the water and the atmospheric humidity are equilibrated, and then the samples are weighed.

[0032] (2) Moisture content of test sample w 1

[0033] Use 16 dry weighing dishes with known mass and constant weight to weigh 8 copies of 3 g of each type of flocculent and roll-shaped balance samples, accurate to 0.001 g, put them in an oven, and dry at 13...

Abstract

The invention discloses a method for rapidly measuring the polymerization degree of refined cotton, which comprises the following steps of: taking a proper amount of refined cotton sample, treating the sample by adopting a high-temperature drying method, and weighing the absolutely dry sample to measure the polymerization degree of the refined cotton. The method for rapidly measuring the polymerization degree of the refined cotton has the advantages of being rapid, simple, convenient and feasible, capable of saving cost, accurate in measured data, high in operability and the like.

Description

technical field [0001] The invention relates to the technical field of polymerization degree measurement, in particular to a method for rapidly measuring the polymerization degree of refined cotton. Background technique [0002] Refined cotton is produced from cotton linters and is widely used as the basic material for the production of cotton cellulose. The main technical performance index of refined cotton is the degree of polymerization. At present, the degree of polymerization of refined cotton (GB / T9107-1999) is tested using the cuproammonia solution method. This test method takes a long time for pretreatment, such as waiting for 4 hours to equalize the sample before measurement. The degree of polymerization cannot provide detection data in time, which directly affects the progress requirements of production and scientific research. Despite its flaws, this method has been used to date because there are no rapid, data-ready alternatives. Contents of the invention ...
